18N to the left and up or down.

#### Explanation:

The net force in the x direction is 10N to the left.

30N left -20N right

Since the 15 force acts perpendicular to the 10 and 20N forces it acts in the y- axis.

Since it is the only force acting in the y direction the net force in the y direction is 15N.

Use pythagorus to find the resultant force.

$\sqrt{{10}^{2} + {15}^{2}} = 18 N$
